It won't run the program because the code is not correct, the same way a C compiler will refuse to compile a missing semicolon. If different indentation changes the meaning of a program from wipe the disk if condition true to wiping regardless of condition, that's a pretty bad change, so the interpreter rightly refuses to run incorrect programs.
